Monitoring how well children’s hearts are developing and working is a challenge because there is so much change as children grow. For example, a small 12 year old may have the same sized heart chambers as a big 10 year old, and the blood pressure results of a 3kg baby will be different from a 50kg teenager’s. Working out whether a cardiogram is normal takes time, and needs access to the available data and information.
To speed this up, the paediatric cardiology team at Evelina Children’s Hospital are working on a smartphone app so that clinicians know straightaway whether the results are normal or not.
Clinicians will be able to enter information like the patient’s age, height, weight, blood pressure, and the app will calculate whether the heart reading is normal, or above or below. It will even give an idea of how serious it is, whether results are just outside the normal range or way out.
As well as quickly highlighting when there is a problem – and providing reassurance when there is not – the app will help to track longer term developments, such as whether a child's aorta (the main artery of the heart) is growing too quickly.
